' ROTARY IXING DEVICE.

Application filed November The object of the present invention is to provide'a novel device adapted to be mounted between. the intake manifold and the car bur-etor of an internal combustion engine, to facilitate the mixture ofair and gas as the air and gas pass from the carburetor to the in the precise embodiment of the invention herein disclosed, may be made within the scope of what claimed, without departing from the spirit of the invention.

in the drawings Figure 1 shows in section, a device constructed in accordance with the invention, parts being in elevation;

Figure 2 is a section on the line 2-2 of Figure 1;

Figure 3 is Figure 2.

The numeral 1 marks the parts of a con duit leading from the carburetor of an internal combustion engine to the intake manifold thereof. The parts 1 of the conduit have flanges 2 between which is located a casing 3. Securing elements 4, such as bolts,'pass through the flanges 2 and through the casing 3, to hold the casing 1n place between the flanges, as shown in Figure 1 of the drawings. The casing 3 may conveniently be made out of laterally separable parts 5 held together by the bolts 4:.

In the casing 3 there is formed a chamber 6, and the casing has. oppositely disposed reduced openings 7 communicating with the chamber 6, theopenings 7 being of approximately the same diameter as the bore of the conduit 1. Cross pieces8 are connected to the casing 3 and extend across the openings 7. In one of the cross pieces 8 an adjustable bearing 9, preferably a screw, is mounted, and the a section on the line of bearing 9 is held in any position to which it may have been ad usted, by

means of anut 19 threaded on the bearing, and adapted to engage the corresponding cross piece 8. In the opposite cross piece 8, one end of a shaft 10 is journaled, the opposite end of the shaft 10 being journaled in the adjustable bearing or screw 9.-

()n the shaft 10 is mounted a rotor which is a composite structure. The rotor includes a foraminous body 11 on oneside of which are trough-shaped vanes 12, that overhang the foraminous body as'shown clearly in Figure 3, the vanes 12 extending outwardly from a central hub 141. As shown at 15 in Figure 2 of the drawings,the vanes 12 are curved, in any desired way, in a direction parallel to the body 11 of the rotor, so that the fuel and air will be directed by the vanes 12 t0 ward the'center of rotation of the rotor '11, that is, toward the axis of the shaft 10. On

the opposite side of the rotor 11 from thevanes 12, are located blades 16 connected to a central hub 18. The blades 16 are disposed radially from the rotor 11, as shown in Figure2. The blades 16 are connected along one longitudinal edge with the foraminous body 11, but, considered transversely, they slant away from the body 11, so that the opposite edge of each blade 16 is at some distance from the body 1.1,"asclearly shown in l igure 8. Nuts 17 are threaded on the shaft 10 and engage the hubs 1 1 and 18 to hold the hubs, and the corresponding vanes and blades, in place on the foraminous body 11 of the rotor.

.The current of air and fuel passing through the conduit 1, turns the rotor. The

vanes 12 carry the mixture inwardly toward the axis of rotation of the rotor, and the blades 16 tend toforce the mixture outwardly away from the center of rotation of the rotor. In thisway, a thorough mixture of fuel and air is brought'about.

that is claimed is In a rotary mixing device, a casing, a rotor.
